The sixteenth century brought about a plethora of changes for the Spanish empire and its conquistadors. They began their conquest of North America as well as their conquest of Central America (mainly Mexico) when Hernando Cortes traveled to Cuba in 1508. He then sailed to the east coast of a new land, now called Mexico, to conquer the native Aztec’s and their immense wealth. Alvar Cabeza de Vaca was the first conquistador, Spanish sailors who were searching for land that could be brought into the Spanish empire, to travel across the southern tip of North America, into the Gulf of Mexico and upon his return to Spain, he published a book or an account with full details as to the climate, topography, and native life (including plants, animals and humans). De Vaca’s transcript brought immense attention to both New Spain (Mexico) and the New World (North America). Two conquistadors that followed de Vaca some years later were Hernando De Soto, who traveled through Florida and became the first European to travel to and discover the Mississippi, which he had aptly named Rio Grande (the great river). Coincidently De Soto died on the banks of the Mississippi with fever and malaria (caught from mosquitoes) in the year 1542. Francisco Vasquez De Coronado, who traveled to New Spain with Antonio De Mendoza and then set out in search of the seven great cities of gold (which he never found), was one of the first Europeans to discover the Grand Canyon, which they thought was at least one mile deep. Although this was not his original goal, it was quite impressive. The Spanish, mainly Nunez Cabeza de Vaca, Hernando De Soto, and Francisco Vasquez De Coronado were the first and most significant North American. Hernando De Soto was born into a rich family, but from a young age he knew that he wanted to go and sail, and become wealthy on riches that have been taken from the New World. De Soto would come across these riches with his first encounter with the Incas. De Soto was on an expedition that was headed by Pizarro. They went to Peru in search of gold. When coming across the Incas, the Spanish realized that to get the gold, they would have to totally conquer the Incan people. After being promoted to captain of the cavalry, De Soto was ordered to capture Cajamarca, where the Incan emperor lived. De Soto, upon his horse, with his men mounted behind him, approached Cajamarca. The Incan people, never having seen horses before, never fought back thinking “the Spaniards were gods because they had animals with silver feet”. The silver feet that they were referring to were nothing more then the horseshoes. The Spanish then took all of the gold out of the city, killed almost all of the Incans, and left the rest to die from disease brought over by the Europeans. De Soto also had planned to make a port that would enable Spain to trade with the flourishing market of China. De vaca had talked about a Northern Sea in his accounts. Upon reading this De Soto set out to build his port here. De Soto searched for three years, and never found the Northern Sea, or enough gold to influence other Spaniards to come to the New World. De Soto did however come across a river the he names the "Rio Grande", but it would later be renamed the Mississippi River. De Vaca traveled to the Americas under the command of a man that he did not always see eye to eye with. His name is Panfilo De Narvaez. Their ship hit a hurricane off the coast of Cuba. After repairs and re-supplying they set sail for Florida. They landed around present day Tampa Bay in March of 1528. Here is where disaster began. Narvaez ordered troops to head inland, while some of the men waited for them in boats off the coast, hoping to meet them later in the trip. The land-based soldiers wore out their welcome in the Indian villages quickly and were chased into the swamp land of Florida where they had to live off the land, the oysters in the ocean, their horses and in some cases each other. “Their food was austere in the extreme-some of the nomadic peoples in this wild region ate insects when there was nothing else”. The men waiting on the boats became tired of waiting and sailed back to Cuba. Narvaez and his men then had to battle their way across flordia, through marshy land, diseases and frequent Indian attacks. Once they made their way to the shore, the group had been reduced to about 80 men. The remaining men then made boats out of trrees and horse hide hoping to sail their way back to Cuba. Once in the ocean, a hurricane developed and blow the rafts back into the shore destroying them, and reducing the numbers further. Initially the natives welcomed the Spaniards into their community, but this welcome was also worn out quickly when, as de Vaca recalled, “half the natives died from a disease of the bowels and blamed us".. For over four years the number of men slowly dwindled as they tried to live in the complex world of the natives in Eastern Texas. The number of men now was down to four, including de Vaca. The names of the other three men were Alonso Del Castillo, Andres Dorantes de Carranca and Estevan (who was an African slave that they brought with them). From here the three men began to head west and south attempting to reach the Spanish empire in Mexico. In doing so, these men of the old world to entered into the New World’s West (west of the Mississippi) and became the first Europeans to do so. The precise route that they traveled on is not clear, but it is thought that they traveled through southern Texas and then into Arizona and then into either Southern New Mexico or the Northern provinces of Mexico, where they were discovered by a group of fellow Spaniards in July of 1536, over nine years after they left Spain in Search of land to claim as a possession of Spain. When the troops found de Vaca and his men he recalled his men as being “dumbfounded at the sight of me, strangely dressed and in company with Indians. They just stood staring for a long time". De Vaca returned to Spain, where he wrote his account of what occurred of the previous 9 years of the exploration
